From Graces Guide

Jump to: navigation, search

1785 With Matthew Boulton, John Vivian was instrumental in establishing the Cornish Metal Co, which sought to buy the entire output of Cornish mines and break the smelting companies' hold over the market for copper ore. Vivian was deputy governor of the company

To avoid competition with the Anglesey suppliers, an agreement was signed between the company and Thomas Williams' Anglesey companies on prices and a division of the market.

By 1787 the Cornish Metal Company was virtually insolvent, due to gross business inefficiency

Thomas Williams effectively took it over, controlling it until its articles of agreement expired in 1792, and giving him great control over the copper market.
